Title: Screwdriving attachment for hand-held drilling machines
Inventor: FUCHS MICHAEL ING GRAD
IPC: B25B21/00
Filed: 1983-06-03
Abstract: A screwdriving attachment for hand-held drilling machines which are usable in particular in right-hand and left-hand rotation is to be improved such that the limit torque desired in each case and the screwdriving attachment can be set in a continuously adjustable manner with a minimum degree of complexity. For this purpose, it is proposed to arrange, between a front pressure disc which surrounds the drive shaft concentrically, is supported by means of sliding elements opposite a carrier plate fixedly connected to the drive shaft and is mounted in the casing so as to be secured against rotation, and a rear spring plate which is guided in the casing so as to be secured against rotation and longitudinally displaceable and is likewise situated concentrically with the drive shaft, a compression spring which is continuously adjustable within its spring range by axial displacement of the spring plate by means of an adjusting device accessible from outside (Fig. 1). <IMAGE>
Patent DE-3324428-A1 (DE)
Title: Pillar drilling machine
Inventor: CUNEO GIUSEPPE
IPC: G05B19/4093
Filed: 1983-07-07
Abstract: A pillar drilling machine has a chuck for tools, which chuck can be lowered vertically by a pivotable control handle via a rack and a pinion. A slotted disc (20), connected to the control handle and movable therewith, runs between a photocell (23) and a light source (24) in order to convert angular displacements of the control handle into coded signals. The signals are added up in a first counter (34) and fed to a digital display (25) in order to convert the data associated with the drill-hole depth reached into a continuous display. An input device (27) supplies, via a second counter (37), a comparator (38) with data corresponding to the desired drill-hole depth. The comparator (38) continuously compares the data of the first counter (34) and the data of the second counter (37). If the compared data coincide with one another, the comparator (38) emits a warning signal in order to actuate a visual and/or acoustic indicating device (25, 39). <IMAGE>

Title: Signal processing method and signal processor
Inventor: BAGLEY GEOFFREY CHARLES
IPC: G01S7/36
Filed: 1983-08-12
Abstract: The subject matter of the invention is a method and a signal processor for processing signals which contain a combination of a low-amplitude wanted signal (Sw) and a higher-amplitude unwanted signal (Su). The input signal is divided in the signal processor between two channels (A and B). A limiter (12; 22) with a variable limitation effect is disposed in one channel, and a variable attenuator (14; 23) and a phase shifter (15; 24) are provided in the other channel in order to match the output power of both channels (A and B) with one another. Both channels (A and B) are then re-combined so that the limited signal interferes with the unlimited signal in order to suppress the higher signal (Su). In a first design variant, the channels (A and B) are combined via a power combiner (16), and a signal delay of  pi  is introduced radially in one channel. In a second design variant, the two channels (A and B) are combined in a mixer (25) and a filter (26). <IMAGE>

Title: Device for adjusting the swivel axle of the joint of a radius arm for guiding a vehicle wheel
Inventor: KLEINSCHMIT EINHARD DIPL ING
IPC: B62D17/00
Filed: 1983-10-11
Abstract: In a device for adjusting the swivel arm of the joint of a radius arm for guiding a vehicle wheel, a bearing bushing of the radius arm joint is mounted on a hinge bolt which is held between carrying legs and is radially adjustable at least in the direction of the longitudinal axis of the radius arm by means of eccentric elements. In order to ensure at any time a sensitive radial adjustment of the hinge bolt despite the occurrence of corrosion between the bearing surfaces of bearing bushing and hinge bolt, the hinge bolt is mounted inside the bearing bushing so as to be free of play only in its end regions and between the bearing points of the bearing bushing an annular gap is present between said bearing bushing and the hinge bolt. In this way, frictional corrosion occurring at the bearing points can be easily overcome when the hinge bolt rotates and corrosion products can collect in the annular gap and thus no longer lead to jamming.
Patent DE-3340837-A1 (DE)
Title: Hand firearm
IPC: F41A21/36
Filed: 1983-11-11
Abstract: In hand firearms which are supported on the body for firing, a shift of the firearm in relation to the target direction occurs during firing because of this type of support. This shift occurs especially in repeated fire. By means of damping devices (15, 16) of the firearm barrel (9, 61) and of the firearm housing (32), which act in the firing direction, and by means of a spoon-shaped nozzle attachment (50), the shift of the firearm caused by the recoil which normally occurs is compensated even only when a single shot is fired, so that a better hit result is obtained. In repeated fire, the floating mounting of the firearm housing (32), together with the firearm barrel (9, 61), brought about by the damping devices (15, 16) ensures a very small spread circle at the target. Moreover, the firearm is relatively steady during firing and can thereby be controlled by the gunner virtually without any force. <IMAGE>
Patent DE-3341659-A1 (DE)
Title: Wheel-chair traction device
Inventor: ROSE WOLFGANG ING GRAD
IPC: A61G5/04
Filed: 1983-11-18
Abstract: The invention relates to a wheel-chair traction device as described in detail in Patent Application P 3200157.6 and represents an additional patent application to Patent Application: P 3301408.6. In practice it has been found that it is not just the wheel-chair occupant himself who wants to operate the traction device but also, at least at times, a person accompanying him. However, the accompanying person walks beside the wheel-chair and would have to bend down low to one side in order to operate the steering linkage of the traction device which, after all, is normally located between the traction device and the wheel-chair. It is the object of the invention to displace the steering linkage of the frame to one side to such an extent that it can comfortably be operated by the accompanying person walking beside the wheel-chair. This object is achieved by the invention in that the whole traction device is displaced toward the side in the travelling direction relative to the wheel-chair, in that the connecting rod which consists, for example, of a rigid pipe, between the traction device and the wheel-chair is located off-centre on one side and has a connection element which can selectively be coupled on a frame component, for example of tubular shape, to the right of the wheel-chair or on such a frame component to the left of the wheel-chair.

Title: Bell lifting valve for flushing-water cisterns
Inventor: ZOELLER HARTWIG DIPL ING
IPC: E03D1/14
Filed: 1984-03-20
Abstract: In order to reduce the unnecessarily high water consumption in WC units or other sanitary fittings, the bell lifting valve is configured such that the part-quantity of water which can be removed can be infinitely selected by hand via a tie rod. The lifting bell is buoyant and can perform limited, vertical upward and downward movements with respect to the standpipe. A clamping device for the tie rod is opened or closed by virtue of these movements and the tie rod is thus released or firmly clamped. One end of a movable pipe which is open on both sides is guided under the edge of the lifting bell or into the lifting bell and is fastened there. The free end of the pipe is loaded by a weight and suspended on the tie rod. The free end of the pipe is positioned in the flushing-water supply via the tie rod and divides said supply into an available part-quantity of water and a residual quantity of water which remains in the flushing-water cistern.

Title: Pull-operated motor-vehicle friction clutch with releasable snap-in connection
Inventor: NITTKE JOACHIM DIPL ING
IPC: F16D23/14
Filed: 1984-04-19
Abstract: The invention relates to a releasable snap-in connection within the release system of a pull-operated motor-vehicle friction clutch. To transmit the release movement, a radially elastic ring is provided which engages in grooves of two concentric components. The ring is held centrally in the groove of the outer component, the said groove being open radially towards the inside, and the inner component is introduced in the axial direction with a cone. The elastic ring travels on the cone as far as a groove of the inner component, the said groove being open radially towards the outside. A connection for the transmission of the pulling release force is thereby established. To release this snap-in connection, the inner component is pushed further into the outer component, counter to the release movement and, as a result, the elastic ring climbs up the conically widening groove base and, during this change in diameter, its two free ends come into circumferential overlap, with the result that this ring can no longer spring back into its original tight position during the pulling-out of the inner component. This makes the release of the snap-in connection simple.

Title: Case profile made of aluminium for frames of transport trailers
Inventor: PALMOWSKI HORST
IPC: B60P3/10
Filed: 1984-05-17
Abstract: The invention relates to a case profile made of aluminium for frames of transport trailers, in particular boat trailers, consisting of two longitudinal members which are arranged one on top of the other with spacing, connected to one another by means of a common web and consist of a box-shaped hollow profile whose surfaces, facing one another, form together with the web a cavity for receiving the one end of transverse members of the frame whose other end can be plugged into the corresponding cavity of a second case profile which is arranged in mirror-inverted fashion parallel to the first case profile. In order to avoid the disadvantages, such as weakening of the profile due to unclean welds and distortion of the frame due to the effects of heat, which have hitherto been caused by the welding together of the members consisting of aluminium, it is proposed according to the invention that the longitudinal members have, in the region of that surface of the transverse member which emerges from the cavity, a wall extension on their hollow profiles, which extension can be permanently connected by rivets or screws to the wall of the transverse member lying opposite this wall extension.

Patent DE-3503007-A1 (DE)
Title: Method for measuring geometrical variables and device for carrying out the method
Inventor: KRAUS HEINZ
IPC: G01B9/02
Filed: 1985-01-30
Abstract: Device for measuring lengths of an object (11), in which partial measurements are carried out using a laser interferometer. For this purpose, a base carriage (BS) moves at constant speed along the measuring distance. In addition, two measuring carriages (MSa, MSb) move alternately, likewise in the measuring direction X. The changes in the spacing between the measuring carriages (MSa, MSb) and the base carriage (BS) are measured alternately by the laser interferometer and processed in an electronic evaluating unit. In order to compensate disturbing environmental influences, the measuring distances (A, B) are surrounded by displaceable hollow bodies (4a, 4b) and preferably evacuated. These hollow bodies (4a, 4b) are connected elastically to the aforesaid carriages (BS, MSa, MSb). A mechanical connection of the hollow bodies (4a, 4b) to a compensating piston (13) has the effect that virtually no reactive forces occur in the hollow bodies (4a, 4b) (Figure 5). <IMAGE>
